BOOK A PRIVATE PARTY
Book your private event at Outer Space Seattle and have the whole space to yourself! Private Parties are a perfect way to let your kids have fun while only being in contact with the people you are comfortable with.
Parties are offered Saturdays & Sundays. Unlisted dates are SOLD OUT. If you would like to book a party in July & August please email us at firstname.lastname@example.org.
Our parties are two hours long and cost $300 plus tax. Parties are for up to 40 people, which includes both adults and children. During the party you are responsible for supervising your guests, so make sure you have enough adults on the premises with you to help if you are having a drop-off party.
Our playground is designed for kids 3-12, but parents are allowed into the playground to assist younger children. We also have lower level activities including a playroom. We provide tables, table covers, chairs, and post party clean up (Yes, we handle the clean up!). Decorations are not included. You may bring food with you - Cakes, cupcakes, donuts all welcome! Please note that we are a peanut-free and alcohol free facility. You may arrive 15 minutes early to set up. $300 plus tax. No walk-in parties allowed. All parties must be reserved ahead of time.
We have our own ventilation system that runs 24/7. This means we do not share the same air as Cactus Restaurant or Locust Cider. We also have added air purifiers and a large garage door that we can open, weather permitting, for fresh air.
Deposit to Book
We require a non-refundable $100 deposit to book your party, which is then applied to the total cost. After selecting your party slot we will email you an invoice via square for online payment of the deposit and party. We do not hold dates unless the deposit has been paid.
Plates, napkins, cups available for $10 fee
Socks are available for $2 a pair
If you cancel your party less than 48 hours before your scheduled event, you forfeit the $100 deposit. We require 48 hour notice to reschedule a party and charge a $25 rescheduling fee. If you have a sick birthday child and need to reschedule, we need to know two days before the party, or as soon as possible. If notification of sick child rescheduling is not given the deposit may be forfeited.
Party Tips & Tricks
We’ve had a lot of birthday parties. We like to think we are experts in the art of party-ing. Here are some of our tried and true tips for a successful party:
✅ Let the kids be kids. Our staff will go over the playground rules upon arrival, but let them have fun and go a little wild. This is the perfect place for them to let out their energy.
✅ Sugar rush is real. We recommend serving your desserts halfway through your party. That way the kids have an hour to burn off the sugar.
✅ Don’t stress the mess. Clean up is included in our party service. Enjoy your party and don’t worry about tidying up, we’ve got it covered!
✅ Party Favors at the door. Saying goodbye is hard. Handing out party favors as kids leave helps facilitate a smooth exit. It also prevents party favors from being left behind.

We just had our daughter’s 6th Birthday Party at Outer Space Seattle and it really is the perfect place to host a kids birthday party. The staff take care of everything, which means you as parents actually have time to spend with your guests. The play structure is super entertaining for kids and the building has a lovely layout for adults to supervise from below, but still have adult conversation. The large windows make for a bright, joyful, memorable, day. Thank you Outer Space Seattle!
